JOSEPH GOEDDEKE, OF DETROIT, MICHIGAN.

MALT-SCOU RING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 432,998, dated July 29, 1890.

Application filed January 3, 1890. Serial No. 335,757. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH GOEDDEKE, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in a Malt-scouring Machine; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in a malt-scouring machine, and has for its object more particularly the scouring of the grain after sprouting to clean the sprouts as well as any other impurities or foreign substances therefrom in a more efficient and desirable manner than has hitherto been accomplished.

To this end my invention consists of the combinations of devices and appliances hereinafter described and claimed, and more fully illustrated in the accompanying drawings, in which Figure 1 is a side elevation showing parts in section. Fig. 2 is a side elevation from the opposite side. Fig. 3 is a detail view showing the adjustment of the shaft of the agitator. Fig. 4. shows details of the construction and operation of the screen. Fig. 5 is a detail view of the drum and adjacent parts. Fig. 6 is a partial plan showing the engagement of the belt with the driving-shaft of the agitator. Fig. 7 is a vertical section of the suction-fan and chute communicating therewith; Fig. 8, a separate view of the drum. Fig. 9 is a horizontal section through the line 1) 1;, Fig. 8. Fig. 10 is a perspective view of one of the blades. Figs. 11 and 12 are modifications thereof. Fig. 13 is a cross-section on the line 1 y, Fig. 10. Fig. 14 is a longitudinal section on the line :0 00, Fig. 10. Fig. 15 is a detail view of the shaft E illustrating its connection with one of the bearings; and Fig. 16 is an enlarged view, in horizontal section, showing the grain both between the blade and the drum and between the blade and the case.

I carry out my invention as follows:

A represents any suitable frame or support.

Bis any suitable screen, which may be operated by an eccentric B.

C is a suction-fan.

D is a driving-shaft, driven by driving-belt D, from which the fan is driven, as by a belt D E is a stationary case; E, an agitator or scourer located therein. This agitatorI prefer to make both rotatable and adjustable. E is the shaft, upon which it is rotatable, the entire agitator being vertically movable in the case, which is made of conical form, so as to set the agitator to do closer or coarser work as may be required to render the operation most satisfactory and efficient. The shaft E is provided with a driving-pulley E and which is driven from the driving-shaft D by a belt D suitably engaged therewith.

In the manner illustrated in the drawings, an auxiliary shaft F is provided, having pulleys f f mounted thereupon, the shaft being properly journaled upon the frame A, as shown at A. The belt D passes over the pulleys f f and about the pulley E such a construction and arrangement making a more compact machine. G is a spout by which the malt is conveyed from the screen B to the interior of the case E. The interior of the case is preferably corrugated or provided with a corrugated metal lining, as shown at The agitatorE consists, more specifically, of a drum E upon the exterior of which Ilocate numerous spring scouring-blades E with their free ends preferably extending upward. I do not confine myself to any definite construction of these blades, as they may be varied in form and in construction, as illustrated in Figs. 10, 11, and 12. They may be cut away or perforated or corrugated or bent in any suitable form to effect the desired result. Thus in Fig. 12 the blade is cut away on one of its outer edges, as shown at e, and recessed, as shown at e 6 In Fig. 10, in addition to the foregoing, the blade is perforated, as shown at e 6 So, also, in Fig.11 the outer end of the blade is corrugated. The blades are engaged upon the rounded surface of the drum at one end by screws e or their equivalents, to exert a yielding pressure upon the grain, so as to permit the grains or kernels of malt to fall in between the blades and the case and between the blades and the face of the drum, and thence to work out between or through the blades, so as to effectually free the grains or kernels of any sprouts or foreign substances. Upon the rotation of the drum the free ends of the spring-blades strike against the corrugation 'of the drum, by which they are kept from clogging.

E is an open disk or rim connected to the drum by means of slats or bars 6, rotatably engaged with the drum and with the disk, so that they may be more or less opened or closed together, as desired, to permit the grain entering the disk to pass outward, downward, and about the revolving drum. To adjust the agitator vertically one of the boxes c has an adjustable engagement upon the frame, as shown at a Fig. 3, and a tongue-andgroove connection with the shaft, as shown in Fig. 15.

Opening beneath the case E is a chute H, having communication with the suction-fan. Said chute is provided with a series of deflectors H H extending from the respective sides thereof to direct the malt back and forth in its descent through the chute. In the side of the chute opposite the fan is a series of openings h, through which a draft of air is sucked by the fan into the chute to more effectually cleanse the malt from impurities.

H is an inner, partition dividing the chute, so as to form a flue H. the chute is separated from the suction-flue leading to the fan by deflectors H H", compelling the malt to descend through the flue H The eccentric B is driven from the driving-shaft by means of a belt D The screen is supported, preferably, upon spring-arms b at its four corners, the motion of the eccentric causing thus a vibration of the screen. The blades are preferably engaged at one end upon the drum in downwardly-inclined rows, as shown in Figs. 1 and 8, the free ends of the blades projecting upward to catch the grains. In Fig. 8 I have only shown a few blades attached to the drum; but those servefor purposes of illustration, it being understood that the drum is covered with blades in the same manner.

WVhat I claim as my invention is- 1. In combination, a case, a rotatable agitator-shaft, a drum mounted thereon, and a At the upper end feed -regulating device consisting of a rim united to said drum by slats, substantially as set forth.

2. The combination, witha rotatable drum, of a series of elongated blades, said series extending in the general direction of the length of the drum and each secured at one extremity only to said drum, leaving a free resilient end at the opposite extremity, substantially as set forth.

3. The combination, with a rotatable drum, of a series of elongated blades, said series extending in the general direction of the length of the drum and each secured at one extrem ity only to said drum, leaving a free resilient end at the opposite extremity, and each blade provided with grain -exit passages formed therein, substantially as set forth.

4. The combination,.with a rotatable drum, of a series of elongated blades, said series extending in the general direction of the length of the drum and each secured at one extremity only to said drum,leaving a free resilient end at the opposite extremity, and each blade provided with marginal recesses and grainexit orifices formed therein, substantially as set forth.

5. The combination, with a rotatable drum, of a series of blades each secured at one extremity only to said drum, leaving a free resilient end at the other extremity, said blades arranged with their free ends projecting up ward, substantially as set forth.

6. In combination, a rotary drum and blades secured thereto and arranged in series which extend diagonally across the drum, thereby forming a continuous rubbing-surface, substantially as set forth.

7. The combination, with the corrugated conical case, of a rotatable conical drum, mechanism for adjusting one with respect to the other, and a series of elongated blades, each secured at one extremity only to said drum, leaving a free resilient end at the other extremity and each provided with grain-exit passages formed therein, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
